An eagle doesn’t flap its wings quickly, using lots of strength; it soars – it is carried by the currents of air. Strength from God doesn’t come by flapping with human energy but from waiting on the Lord, with faith and patience.
Waiting isn’t inactivity. The eagle doesn’t just sit there; it flies and then is carried by the wind. In the same way, we don’t just sit around: while we are waiting on the Lord, we move forward in obedience. We get on with serving God, loving our neighbours, worshipping, working at the things that God has given us to do. As we trust, and patiently wait, and as we serve, worship and rejoice in the Lord (“The joy of the Lord is your strength” – Nehemiah 8:10), He will give you strength.
“They will run and not be weary, they will walk and not faint.”
This is a promise that God will supply strength for all that we need. There are times when we are busy (like we are running) and there are times when we are walking in steady obedience. At all times, we can call on the Lord to renew our strength and He has promised to answer.
“And my God will supply every need of yours according to His riches in gory in Christ Jesus.” (Philippians 4:19)
